Definitions

  • the present invention relates to an apparatus for portion cutting of products, such as food products, said apparatus comprising cutting means for sectioning the products; scanning means for detecting at least one characteristic of the product; conveying means for transporting the product from the scanning means to the cutting means; and control means for controlling and regulating at least one relevant cutting process parameters in order to achieve predetermined product portions based on the detected product characteristics.
  • a machine for portion cutting of food products which comprises a rotatable cutting unit for sectioning the products, which are guided through the cutting unit by a first and second conveyor respectively.
  • a vision system for detecting the geometry of the products is arranged by the first conveyor.
  • the form of the products is registered in a control system that can control the machine for portion cutting the products into a predetermined weight, length or size based on the shape of the products and control the conveying velocity of the first conveyor.
  • Such an apparatus a so-called portion cutter, is used in particular in the food processing industry for cutting fish, poultry, pork or beef products into predetermined portion types and sizes.
  • the products are guided on a conveyor and scanned in a vision system.
  • the cutting rate of the cutting unit is controlled, so that the portions or slices become uniform or in a predetermined size, so long as no relative movement between the products and the conveyor occurs between the vision system and the cutting unit.
  • the conveying means comprises at least one conveyor unit having two substantially parallel conveyors each having an upper conveying surface, said upper conveying surfaces being inclined relative to each other, so that the conveying surfaces of the conveyors have a mutual angle different from 180° in a traverse direction of the conveying direction.
  • a reliable portion cutting apparatus wherein food items, such as pork, beef or fish, are handled gentle and efficiently and it is ensured in a simple manner that the items are kept stationary relative to the conveyors during the processing of the items, and in particular may be sectioned into predetermined portions in a precise manner.
  • the conveyor unit between the scanning and the cutting stations in a portion cutter with a V-shape, as it is the case with a portion cutter according the invention, a precise cutting may be achieved since the products are supported in a stabile manner. This means that the holding means are not needed. This in turn reduced the amount of conveyor belts or similar equipment making contact with the food product, which increases the food safety in hygienic terms, just as any squeezing or pinching action in not inflicted on the food product.
  • the conveying means comprises a first conveyor unit for receiving the products and downstream of the first conveyor unit a second conveyor unit, which takes the products to the cutting means and a third conveyor unit, which transports the sectioned products away from the cutting means.
  • both the first, second and third conveyor unit comprises two parallel mutually inclined conveyors, and that the parallel conveyors of the conveyor units are arranged with the same mutual inclination in each of the conveyor units.
  • Other feeding and discharging conveyor units may be used.
  • a conveying surface is provided which is not planar. This results in an automatic alignment of the products on the conveyor units and ensures that no relative movement occurs between the products and the conveyors in the conveyor units, as the products rest on two sides of the conveyors.
  • the use of the apparatus is particularly useful for products that easily move, e.g. roll or tilt, or more generally products without a flat side; however, it is realised that the portion cutter according to the invention is also useful for cutting flat items, such as fish fillets or the like. It is realised that somewhat elastic products, such as pre-cooked meet products or the like, may advantageously be cut into portions by use of a portion cutter according to the invention.
  • the scanning means are arranged between the first and the second conveyor units and preferably include a scanner adapted to perform a 360° scanning of the products.
  • a scanner adapted to perform a 360° scanning of the products.
  • the two mutually inclined pair of conveyors of the conveyor unit or units are preferably both inclined with the same angle relative to horizontal forming a V-shaped conveyor configuration.
  • the angle of inclination of the pairs of conveyors is preferably also adjustable, preferably between 0° to 40° relative to horizontal, so that a V-form with a mutual angle of the upper conveyor surfaces is preferably between 100° to 180°.
  • the angle of inclination may be automatically adjustable so that the control system of the portion cutter apparatus may adjust the inclination of the conveyor units e.g. in response to a batch with a particular product size.
  • the adjustment may be adjustable by means of an actuator mechanism or the like acting on one or more of the conveyor units.
  • common drive means are provided for driving the pair of mutually inclined conveyors with the same conveying velocity.
  • each of the conveyors is provided with an elastic conveyor belt having an inclined upper conveying surface over a support structure and a lower run where the belt is turned to a horizontal configuration where the belt is engaged by the drive means.
  • the drive means preferably includes a drive roller with engagement pins cooperating with traction holes in the conveyor belt; said conveyor belt being held in tension support rollers by leading the belt in a loop run over the drive roller. Thereby it is ensured that the belt may be driven at a very precise conveying velocity.
  • drive rollers of the adjacent two conveyors in a conveyor unit are arranged on a common drive shaft. This further ensures an exact speed of both conveyor belts in the conveyor unit and that the two conveyors are driven synchronously.
  • the control means is adapted to regulate the conveyor velocity of the conveyor unit and/or the rate of the cutting means in response to a computation of the input of the scanning means and predetermined portion type information.
  • the control means hereby automatically adjust the conveying speed and the rotation of the cutting knife so that the product is cut at predetermined locations and into portions of predetermined sizes.
  • the cutting means includes a rotating knife that is positioned to cutting the products between the second and third conveyor units.
  • a rotating knife that is positioned to cutting the products between the second and third conveyor units.

  • the preferred embodiment of an apparatus comprises three conveyor units 3 , 4 , 5 , which are arranged in alignment next to each other on a support structure (not shown).
  • the entire apparatus is encased in a housing (also not shown).
  • a scanning device 6 is provided between the first and second conveyor units 3 , 4 .
  • This scanning device is preferably adapted to perform a 360° scanning of the items 1 , which pass through the scanning plane from the first conveyor unit 3 to the second conveyor unit 4 .
  • the shape of the item 1 is detected and the three-dimensional shape of the item is calculated.
  • This three-dimensional computer presentation may be created and stored in a control system and used for calculating the cutting of the item into predetermined sizes by the cutting unit 2 , which is provided between the second and third conveyor units 4 , 5 .
  • the cutting unit 2 comprises a rotating knife 10 , which is driven by a motor 12 .
  • the control system (not shown), the conveying velocity and the timing of the rotation of the knife is controlled, so that the portion cutting is carried out according to a predetermined portion cutting profile which is stored in the control system.
  • the control system is also provided with the characteristics of the item, such as kind of food item, density, total weight (which may be determined on a flow weight positioned upstream the portion cutter), desired portion sizes, etc.
  • a holding belt 7 is provided at the end of the second conveyor unit 4 .
  • This holding belt 7 is pressed against the top of the item and retains the items 1 during the cutting action and prevents the items from moving during the cutting.
  • the inclined conveyor belts makes the need for a holding belt obsolete, as shown in FIG. 2 .
  • This is furthermore advantageous as the slight pressing force exercised by the holding belt on the item may damage the items, in particular if the items are light meet, such as turkey meet, the item may be compressed which results in an imprecise cutting.
  • the holding belt may compromise the surface of the item in particular if the belt is provided with small spikes as the usually are.
  • Each of the conveyor units 3 , 4 , 5 comprises two conveyors 3 a, 3 b; 4 a, 4 b and 5 a, 5 b.
  • the two conveyors 3 a, 3 b; 4 a, 4 b and 5 a, 5 b are mutually inclined so that the conveyor surfaces 40 , 41 (see FIGS. 3, 4 and 7 ) are provided in a V-shape, as shown in the figures.
  • all three conveyor units 3 , 4 , 5 are provided with a V-shape, but it is realised that only the second conveyor needs to be V-shaped in order to achieve the basic advantage of the invention, i.e. that the items do not move on the conveyor after the scanning and before the portion cutting.
  • FIGS. 9 and 10 other alternative embodiments of a conveyor unit in an apparatus according to the invention are shown.
  • FIG. 3 is shown an embodiment with one conveyor belt 13 , which is turned into a U-shape over two sets of rollers 14 a and 14 b.

  • items such as a food product, e.g. fish, beef, pork, turkey or the like, is placed on the first conveyor unit 3 preferably with a relatively short distance between the items.
  • the first conveyor unit 3 forwards the item to a vision system, such as a ring scanner 6 .
  • a vision system such as a ring scanner 6 .
  • the scanning device 6 has detected the front end of the item, the second conveyor unit 4 , and the holding belt 7 (if mounted) and the third conveyor unit 5 are driven with a conveying velocity in dependence of the velocity of the first conveyor unit 3 .
  • the second and third conveyor 4 , 5 and the holding belt 7 is stopped whilst the first conveyor unit 3 continues to run until items are again detected in the scanning device.
  • the control system keeps track of where the individual items start and stop, i.e. their exact positions.
  • the third conveyor unit 5 may also be driven with a faster velocity than the others whereby it may also be provided that the cut out portions are “pulled” from each other.
  • the knife 10 cuts through the item while the second and third conveyor units run. Typically, the knife 10 will be stopped in a position opposite the cutting area, and is accelerated in a swing to its maximum angular velocity within half a revolution. The activation of the knife 10 is controlled by the control system (not shown).
  • the cutting means preferably comprises a rotating knife, as shown in the FIGS. 1 and 2 .
  • a rotating knife as shown in the FIGS. 1 and 2 .
  • other kinds of sectioning means by cutting such as sawing a band saw, disc saw, etc. or a drop knife, ultra sound cutting, water jet cutting or laser cutting, just as knives with different shapes may be used dependent of the particular cutting task, i.e. what kind of food items that is to be sectioned.
  • the outlet conveyor i.e. the third conveyor unit 5 could be flat as the items are cut at this stage and it is therefore not of the same importance that they are stationarily positioned on the conveyor.
  • a common drive motor is provided for the right and left side of the angularly disposed conveyor unit, as shown in FIGS. 3 to 7 . In this manner, the speed of the conveyor belts is exactly the same ensuring that the items are not turned during their conveying.
